The upper belvedere is easily attainable with a free bus from the Byron square. From the upper belvedere you can see very well the first jump of the fall and the whole valley. A good place where to see the fall is the specola built by the pope Pio VI in 1787.
The best place where you can admire the spectacular falls is the lower belvedere next to Byron Square (car park). From this point you can see all the three falls in the whole height of 165 meters.
Today the water in the canals above the falls is diverted to the hydroelectric power plant of Galleto built in 1929 and its capacity is about 530 MW. For this reason the flow in the falls themselves is reduced to the level of a creek for most of the time of the day.
To regulate the operation of the plant and to allow its vision everybody, in schedules and defined periods, the fall is made to work to the maximum course assuring a spectacular effect.
An acoustic signal tells the opening of the gates of regulation, and the small stream turns him into few minutes in a great river that falls in the void.
The time where you can see the full waterfall is on the web site.
Here you can view where the Marmore's waterfall are situated. They are in the middle of Italy in Umbria in Terni's province.
They are the red star you can see it in the map.
Favorite thing: The admittance ticket costs 5000 ITL (2,58 EUR); it includes the park of the car. From the parking follow the paths and you'll reach the lower point of waterfalls. The ticket includes also a bus for going from the lower to the upper side of the waterfalls.
